[Eduardo Osorio]

Hi,

i wonder if there's some howto information to 
bridge ppp0 to eth0

my distribution is a Hoary Ubuntu 5.04

i install :    apt-get install bridge-utlis

what i need it's connect to internet thru a modem 56k (ppp0)
and then give internet access to my laptop thru a crosspair cable
attached to a eth0 in my linux box .

i was following the article
http://www.linuxjournal.com/article/8261

does anyone knows where i can find that information

You will have better luck using routing and NAT to do this.
Otherwise, your ISP will have to allow multiple IP's over a single
PPP connection.

There is an interesting article covering bridging, but
I think the interfaces are considered to type of
ethernet, no ppp ever considered!

http://www.linuxjournal.com/article/8172

The problem with ppp is that for the dial-up, as I
understand, ppp is NOT over eth (PPPoE), but rather
over some specific Data Link Layer described in V.90
standards.

As I also understand, the web portal for dial-up is on
the linux machine, where the whole process of PAP/CHAP
and autentification with ISP takes place. The ISP
assigns dynamic IP address to dial-up interface, so
NAT is required to maintain xla to private subnet
residing on the ethernet interface.

Then, every node of private subnet will automatically
have access to the internet.

Routing is the magic word. :)
